MACHINE FOB FORMlNG ORNAMENTAL DESIGNS UPON WOOD.

SPECIFICATION forming part of Letters Patent No. 232,823, dated October5, 1880.

Application filed March 8, 1880. (Model) To all whom it may concern:

Be it known that I, JOHN P. JAMISON, of Cambridge, in the county ofMiddlescx and State of Massachusetts, have invented certain new anduseful Improvements in Machines for Forming Orl'iamental Designs uponWood and other Material, of which the following, taken in connectionwith the accompanying drawings, is a specification.

My invention relates to a machine for forming ornamental designs inintaglio on wood, ivory, metal, or other non-flexible material; and itconsists, first, in the combination of a typecylinder mounted inadjustable boxes, which may be raised or lowered to adapt the positionof said cylinder to the thickness of the stock to be operated upon, andan impressioncylinder mounted in bearings in movable boxes resting uponpivoted levers, and a treadlc so connected to said pivoted levers thatthe impression-cylinder may be dropped away from the type or diecylinder to permit the insertion of the object to be ornamented, andthen be raised to press the work against the type or die with thedesired pressure and sufficient flexibility of action to permit theimpression cylinder to accommodate itself to slight variations in thethicknesses of the two edges of the piece of stock being operated upon.

It further consists in a peculiar construction of the type or diecylinder or drum, and the ornamenting-die to be secured thereon, wherebysaid die may readily be secured to or removed from said cylinder, aswill be more fully described.

It further consists in the combination, with the die andimpressioncylinders, of an adj ustable gage located in front of said cylinders,and adapted to support one end of the stock to be operated upon andlocate it in the desired position in the direction of its movement whenbeing acted upon by the die.

It further consists in the combination, with the die and impressioncylinders, of an adjustable gage adapted to locate the stock in thedirection of the length of said cylinders and guide it in its passagebetween them, and an adjustable gage located in front of the cylindersand adapted to locate the position of the stock in the direction of itsmovement when being acted upon by the die and permit a free movement ofsaid stock away from said gage when it is seized by the die.

It further consists in the combination, with an adjustable type or diecylinder, of a driving'pulley and a crank, one or both, and gearin g forimparting to said cylinder a rotary motion, all mounted upon an armsecured to or forming a part of one of the boxes, in which said'cylinderhas its bearing, and adapted to be raised and lowered with saidcylinder.

It further consists in the combination, with die and impressioncylinders located between the frames of the machine, of a secondary dieroll or disk mounted upon the die-cylinder shaft outside of the frame,and adapted to be adjusted endwise thereon and a secondary im* pressionroll or disk mounted upon. an adjustable arbor outside of the frame, andadapted to support the material while being acted upon by said secondarydie-roll, said secondary rolls being designed for ornamenting longstrips and spaces between raised ribs that could not be readily done bythe main die-cylinder.

It further consists in the combination, with the secondary die andimpression rolls or disks, of a device for limiting the upward movementof the opposite end of the shaft which sup ports the secondaryimpression-roll, and upon which the main impression-cylinder revolves,as will be more fully described.

It further consists of a die-roll made in the form of the i'rustum of acone, in combination with an impression-roll having a similar form andan adjustable center, all arranged and adapted for applying circularbands of ornamentation to table-tops or other circular work.

Figure l of the accompanying drawings is a plan of a machine embodyingmyinvention. Fig. 2 is a front elevation; Fig. 3, an elevation of theright-hand end Fig. 4, an elevation of the left-hand end. Fig. 5 is apartial front elevation, showing the machine adapted to ornamentin gcircular work. Fig. 6 is a 1011- gitudinal section of the die-cylinder.Fig. 7 is a vertical transverse section on line 00 w of Fig. 6. Fig. 8is a plan of the die-cylinder with die removed. Fig. 9 is a transversesection of the die-cylinder shaft, and showing the die-gage inelevation. Figs. 10 and 11 are, too respectively, an elevation and endview of a stop-block, to be hereinafter described.

A A are the side frames of the machine, connected together by thetie-rods or girts B B and B, and having formed therein the slots 0 andO, to receive the boxes D and D, respectively, so arranged and fittedtherein that they may be moved up and down therein, as will behereinafter described. The boxes D D are suspended from the upper partof the frames A A by means of the thumb-screws E E, which work in femalescrew-threads cut in the crossbars of said frames above the slots 0 G,and have their lower ends fitted to sockets in the upper sides of theboxes D D, and connected thereto by means of pins, which engage withcircumferential grooves formed in said screws, so that said screws maybe freely revolved therein and cause said boxes to rise or fallaccording to the direction in which said screws are revolved, all in awell-known manner.

F is a shaft mounted in bearings in the boxes D D, and having securedthereon, between said boxes, the die cylinder or drum G, and upon oneend, outside of the frame, the spurgear wheel H, and having formed uponits other end, which. extends some distance outside of the frame, themale screw-thread a, as a means of securing thereon supplementarydie-rolls, to be hereinafter described.

One of the boxes D has secured thereon the arm D which projectshorizontally toward the rear, and carries at its end the stud 1), uponwhich are mounted the pinion I, pulley I, and crank 1 all connectedtogether, so as to revolve together upon said stud, the teeth of thepinion I meshing into and imparting motion to the spur-gear wheel H,said pinion and pulley rising and falling with the die-cylinder as thesame is adjusted to adapt it to different thicknesses of stock.

J J are two levers pivoted to the inner sides of the frames A A infrontof the slots G O, and extending horizontally toward the rear of themachine, where their rear ends are connected by the links J J to therear ends of the treadle-levers J J which are mounted upon and moveabout the tie-rod B, and have their front ends connected by thepedal-board J as shown.

Each of levers J is provided with a projecting lug, 0, upon its outerside, the upper edge of which is made in the form of an inverted V, toform a sort of knife-edge, upon 1 which the box D rests in such a mannerthat a movement of the treadle-levers J 2 will cause the boxes D D torise or fall.

The boxes D D are connected together by the shaft or bar K, securedtherein in such a manner that it cannot be revolved, and has mountedthereon between the frames A A the the impression cylinder or drum L,which revolves freely upon said shaft whenever it is brought to bearupon'a piece of stock, so as to force it in contact with the die, andthe diecylinder is revolved.

The die-cylinder Gr, secured upon its shaft by the screw 61 has formedin the center of its length a dovetailed circumferential groove, d, towhich is fitted a correspondingly-shaped lug, e, which is attached toand projects inward from the inner face of the die-plate M, which mayhave formed upon its outer face any desired ornamental design in relief,the groove (1 being enlarged, as shown at d in Fig. 8, to permit theinsertion of the lug 0 into the groove d, which serves to hold one endof the die-plate, while the other end is secured in position by a singlescrew, 0, which screws into a threaded hole in the cylinder G, as shownin Fig. 7.

By this construction of the die-cylinder and the die to be securedthereon dies of varying lengths may be readily and easily applied to thecylinder and secured in position thereon by the single screw 0, the lugc accommodating itself to any desired position inthe groove d.

The shaft F has secured thereon,just inside of the right-hand box D, thecollar or disk N, in such a manner that it may be adjusted around saidshaft and secured in any desired position thereon, the means shown forthe purpose of securing said disk being the clam pscrew f.

A gage line or crease, g, is made upon the periphery of the collar N,which, incombination with the gage h, secured to the box D in front ofsaid collar, serves as a means of determinin g the proper position ofthe die when the material to be ornamented is brought in contacttherewith by raising the impressioncylinder preparatory to feeding saidmaterial between the die and impression-cylinder to transfer the designupon the die to the wood or other material, and thus insures the properlocation of the design upon the material.

-0 is a horizontal arm projecting outward from the front edge of theleft-hand frame A, and may be of any desired length, according to thework to be done upon the machine. Upon this arm 0 is adj ustably securedthe gage 0, provided upon its inner edge with the inwardly-projectinglip t, the upper surface of which is at a lower level than the main partof the gage, the inner edge of which forms a shoulder, 43, against whichone end of the piece of material to be ornamented (if long and theornamentis tobe placed near one end) is placed so as to rest upon thelip t, while the other end rests upon the impression-cylinder L, withone edge against the gage P, which may be adjusted laterally to anydesired position upon the threaded rod P by means of the nuts j and j,and is adapted to move about said rod as the cylinder L rises or falls.

The object of mounting the gage 0 upon the side arm, 0, and making itadjustable thereon instead of upon a table, is that the operator mayhave free access to the work, whether it is long or short, which isquite a desirable feature, as with the arrangement shown and describedhe can stand immediately in front of the machine, with the gage 0between him rzo and the cylinders, he standing at a. greater or lessdistance from said cylinders, according as i the stock to be ornamentedis longer or shorter.

In the rear of the die-cylinder G is thesizing or inking roll Q, andabove it the distrib uting-roll Q, both mounted inmovable or ad-'ustable boxes on the rods Q 2 or in anv. J

other well-known manner, so that sizing or ink placed upon the roll Qmay be transferred to the surface of the die or type plate when it isdesired to ink or gild the design.

R is a secondary (lie-roll adj ustabl y secured upon the threadedportion of the shaft F by means of the nuts 70 and 7c, and designed moreespecially for applying a continuous line of ornamentation to longstrips of wood or other material which are passed between it and thesecondary impression -roll S, mounted upon and adapted to revolve aboutthe adjustable non-rotatin g arbor S, carried by the upwardlyprojectingarm S adjustably secured upon the projecting portion of the non-rotating shaft K, as shown in Figs. 2 and 4:.

When the strip of material to be ornamented by the secondary die-roll Ris of even thickness, the rolls R and S will be arranged relative toeach other, as shown in full line in Fig. 2 but when it is desirable toornament a strip the two opposite sides of which are not substan tiallyparallel to each other, the roll R is so adjusted on shaft F as to workin conjunction with a circumferential beveled groove, 1, formed on rollS, adapted to support the strip in such a position that the surface tobe acted upon by the die will lie horizontally or substantlally parallelwith the surface of the die, which will be adjusted to a positiondirectly over said groove, as shown in dotted lines in Fig. 2.

The stand or arm S is secured in the desired position on the shaft orbar K by the set-screw m, and the arbor S is secured in position in saidarm by the set-screw m, while the im pression-roll S revolves thereonbetween the collars n and n, which are held in the desired position onthe arbor by the set-screws 12 When the secondary die and impressionrolls are in use for ornamenting long strips, as above described, thepressure upon the impression-roll S has a tendency to cause theright-hand end of the shaft K to rise too high, and thus throw saidimpression-roll out of its true position relative to the die-roll R, tocounteract which I place upon the top of the righthand box D astop-block, T, (shown in detail in Figs. 10 and 11 and in dotted line inFig. 2,) said block being made of such a thickness for each job as willpermit the right-handend of said shaft to rise no higher than thelefthand end, said block coming in contact with the upper end of theslot 0 at the same time that the impression-roll S has forced the stripof wood or other material with sufficient force against the die-roll R.The die upon the roll B being continuous, or extending entirely aroundsaidroll, and intended to place upon the strip of wood or other materiala oontinit ous line of ornamentation, no gage is required to locate thematerial endwise, as it can be entered at any point in the revolution ofsaid dieroll, the plate 0 serving as a side gage to determine thedistance of the ornament from the edge of the strip when said strip isof an even thickness; but when one edge is thicker than the other theside of the groove l serves the purpose of a guide, the rolls It and Sbeing adjusted so as to bring the groove l beneath the roll R, asindicated in dotted lines in Fig. 2.

When it is desired to place upon a table top or other circular piece ofwood or other material a circular line of ornamentation, the die-roll Rand impression-roll S are exchanged for the conical die and impressionrolls U and V, respectively, as shown in Fig. 5.

The circularpiece of material to be ornamented is placed between theconical. rolls U and V, with its center resting upon the conicaladjustable center-point p and its periphery resting against thegage-plate 0, as indicated in dotted lines in Fig. 5, when the rotationof the conical die-roll U will cause the piece of material to rotateabout the center 19 in an obvious manner.

A secondary ink distributing roll, W, is mounted upon the shaft of theroll Q, and a secondary inking-roll, WV, is mounted upon a stud, 0, setin the adjustable arm or plate 0 which rolls W'and Wserve to ink or sizethe surface of the dieroll R, all as shown in Figs. 2 and 4.

When the conical die and impression rolls are used the inking andink-distributing rolls W and W are displaced by suitable conical inkingand distributing rolls, one of which viz., the inking-roll-is shown at Xin Fig. 5.

By the use of my machine designs for ornamentation or the name andaddress of the manufacturer may be transferred to any desired portion ofa panel or other piece of stock to be used in the structure of musicalinstruments, furniture, or other wood work, and upon ivory or metalplates of any desired thickness from the thickness of paper to two orthree inches in thickness, it being understood that the dies for useupon metal should be made of steel and hardened, as described in LettersPatent N 0. 198,847, granted to me January 1, 1878.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is

l. The combination of a die-cylinder adapted to be adjusted to a higheror lower level to adapt it to stock of widely-varyin g thicknesses, animpression-cylinder adapted to be moved toward and from saiddie-cylinder, one or more gages to locate the stock, and a treadlemechanism connected with and adapted to move said impressioncylindertoward the die-cylinder and (letermine the pressure between them,substantially as described.
